The Rice University Neologisms Database

When you have AP-ed out of a class, it means that you already have credit for that course from taking an AP test. Many high schools offer these AP, or Advanced Placement, exams at the end of the year, and the material is supposed to be equivalent to a college course in that subject. The scores range from 1 to 5, and Rice University gives students credit for exams with a score of 4 or 5. At Rice, this credit is either for a specific class, or just blank credit contributing to your total number of hours. This term probably originated because it is very wordy to say "I took the AP exam for that course and got credit for it" every time you discuss a class for which you have done this. The term "Advanced Placement Test" had already been shortened to "AP test" before this neologism was formed. The new term was formed by taking the noun "AP test" and clipping off "test". Then, the verb ending "-ed" is added along with "out".
